Storage apparatus with a breachable flow conduit for discharging a fluid stored therein
Apparatus 10 has breachable flow conduit 12 for discharging stored fluid 12F contained in storage chamber 10C out to the ambient. Chamber access region 10R is positioned proximate perimeter 10P of the apparatus. The breachable flow conduit is within the access region, and has an inner end 12C proximate the storage chamber and an outer end 12P proximate the perimeter of the apparatus. The flow conduit has outer pressed seal 14P between the outer end of the flow conduit and the perimeter of the apparatus. The flow conduit also has inner pressed seal 14C between the inner end of the flow conduit and the edge of the storage chamber. The flow conduit expands towards the perimeter of the apparatus under external pressure, typically applied by the consumer. The pressure causes the flow conduit to breach at the perimeter of the apparatus. The flow conduit also expands towards the storage chamber. The pressure causes the flow conduit to breach at the edge of the storage chamber. Breached flow conduit 13B establishes fluid communication between the storage chamber and the ambient for discharge of the stored fluid.
This invention relates to a storage chamber having a flow conduit for easy discharge of a fluid stored therein, and more particularly to a bubble type flow conduit which is double-breached for accessing out to the ambient and into the chamber.
BACKGROUNDSimple product bags or pouches in common use, such as milk and water containers, typically do not have a pouring spout or even a provision for opening the bag. The user manually rips off a small corner piece or punctures the bag with a pointed tool, creating jagged opening into the storage chamber. Pouring from such a crude opening is awkward, causing loss of contents.
U.S. Pat. No. 6,726,364 issued on Apr. 27, 2004 to the present inventor shows a breaching bubble which provides opposed peel flaps along a perimeter breach. The flaps are peeled back by the user to open a chamber and present a product. The subject matter of U.S. Pat. No. 6,726,364 is hereby incorporated by reference in its entirety into this disclosure.
SUMMARYIt is therefore an object of this invention to provide a storage apparatus having a storage chamber with a breachable flow conduit for discharging the chamber. The flow conduit is breached at each end establishing fluid communication between the ambient and the storage chamber. This controlled breaching provides a controlled opening and controlled pouring
It is another object of this invention to provide a storage chamber for such an apparatus which may be accessed without tearing or puncturing, and without tools for cutting or puncturing. The flow conduit may be breached by applied pressure from the user's thumb and forefinger.
It is a further object of this invention to provide such a breachable flow conduit which promotes a directed laminar flow with minimum turbulence. Surface drag along the length of the flow conduit collimate the flow into a uniform discharge.
It is a further object of this invention to provide such a flow conduit having an easily regulated flow rate. The flow may be temporarily stopped by pressing the conduit closed. The pinching permits metered amounts of stored fluid to be released. Parallel flow conduits of varying flow capacities may be employed to obtain a particular flow rate.
It is a further object of this invention to provide such a flow conduit with enhanced barriers to fluid communication and discharge. A single long conduit may be sectioned into shorter conduits creating additional seals between chamber and ambient which must be breached.
Briefly, these and other objects of the present invention are accomplished by providing an apparatus for discharging a stored fluid contained therein out to the ambient. A storage chamber contains the stored fluid. A chamber access region proximate the perimeter of the apparatus, has a breachable flow conduit with an inner end proximate the storage chamber and an outer end proximate the perimeter. The flow conduit is formed by opposed laminae pressed into sealing engagement, forming an outer pressed seal and an inner pressed seal. The flow conduit expands towards the perimeter of the apparatus until the flow conduit creates a perimeter breach from the flow conduit out to the ambient through the outer pressed seal. The flow conduit also expands towards the storage chamber until the flow conduit creates a chamber breach from the flow conduit into the storage chamber through the inner pressed seal. The flow conduit is breached at both ends to establish fluid communication between the storage chamber and the ambient for discharge of the stored fluid.
Further objects and advantages of the storage chamber and the flow conduit, will become apparent from the following detailed description and drawings (not drawn to scale) in which:

REFERENCE NUMERALS IN DRAWINGSThe table below lists the reference numerals employed in the figures, and identifies the element designated by each numeral.
Apparatus 10 has breachable flow conduit 12 for discharging stored fluid 12F contained in storage chamber 10C out to the ambient. The apparatus may be formed by upper lamina 10U and lower lamina 10L pressed into a sealing engagement to form bubble type flow conduits. Chamber access region 10R is positioned proximate perimeter 10P of the apparatus. The breachable flow conduit is within the access region, and has an inner end 12C proximate the storage chamber and an outer end 12P proximate the perimeter of the apparatus. The flow conduit has outer pressed seal 14P between the outer end of the flow conduit and the perimeter of the apparatus. The flow conduit also has inner pressed seal 14C between the inner end of the flow conduit and the edge of the storage chamber. The flow conduit expands towards the perimeter of the apparatus under external pressure, typically applied by the consumer. The pressure separates the opposed laminae of the outer pressed seal until the flow conduit breaches at the perimeter of the apparatus creating a perimeter breach 13P from the flow conduit into the ambient through the outer pressed seal. The flow conduit also expands towards the storage chamber under the applied pressure. The pressure separates the opposed laminae of the inner pressed seal until the flow conduit breaches at the edge of the storage chamber creating a chamber breach 13C from the flow conduit into the storage chamber through the inner pressed seal (see
The flow conduit may be elongated, extending across the access region from the perimeter of the apparatus to the edge of the storage chamber. The flow drag along the sides of the conduit urges the flowing fluid into a laminar flow with minimal turbulence. The discharged fluid flows out of the conduit in a stream that can be directed.
The entire apparatus including both the storage chamber and the access region may be formed by the opposed laminae pressed into sealing engagement, which simplifies manufacture. Alternatively, only the access region, or just the flow conduit, may be formed by the pressed lamina material. The storage chamber may be formed of different material, avoiding long standing exposure of the stored fluid with the laminae material. The lamina material may be any suitable material such as plastic, paper (with wood and/or cotton content) fabric, cellophane, or biodegradable matter. A thin web made of materials such as mylar or plastic or aluminum, forms a flexible film with hermetic properties, and is commonly used as a tear-resistant packaging material.
The stored fluid may be any flowable liquid, syrup, slurry, dispersion, or the like. Low viscous fluids will flow under gravity downward out the storage chamber through the breached conduit out to the ambient. Higher viscous fluids may be squeezed out of a flexible bag chamber and through a breached conduit, like toothpaste. In addition, the stored fluid may be any pourable powder such as sugar, salt, medications, or the like, that can pass through the flow conduit. The particles of the powder roll, slide, cascade and tumble past each other in a fluid manner. Some powders may require a tap or shake of the apparatus in addition to gravity for discharge from the storage chamber. The outside ambient may be the general space or location of the consumer which is ordinary air. Alternatively, the ambient may be a controlled space, such as the inside another container or a space submerged under another fluid.
Opening the ApparatusThe flow conduit is expandable by external pressure applied by a consumer, to establish fluid communication from the chamber out to the ambient. The inner and outer seals may be breached separately by pressing twice, once at each end of the conduit. Alternatively, these seals may be breached simultaneously by pressing once in the center of conduit. For small conduits, the consumer may simply pinch the conduit or conduits between his thumb and finger. Slightly larger conduits may require thumb pressure against a hard surface such as a table. The consumer may direct the conduit expansion outward towards the ambient at perimeter 10P of the apparatus by applying pressure along outer end 12P of flow conduit 12 proximate point “P” (see
The outward expansion of the conduit progressively separates the opposed laminae of outer seal 14P, along a moving separation frontier. The frontier moves across the outer seal until the frontier reaches the perimeter of the apparatus, where the conduit breaches creating perimeter breach 13P (see
The inner seal may be stronger than the outer seal due to a higher temperature and/or pressure and/or dwell-time during seal formation. That is, the inner seal may be fused together more than the outer seal. The outer seal may be breached first forcing conduit gas into the ambient. As the inner seal is breached, the conduit is pressed closed, preventing the loss of any stored fluid.
Barricade Dam—(FIG. 2)The flow conduit may have a barricade dam which presents additional pressed seal type barriers between the ambient and the chamber containing the stored fluid. In the embodiment of
The apparatus may have multiple flow conduits for providing multiple breaches establishing multiple fluid communications between the storage chamber and the ambient for multiple discharge flows of the stored fluid. Apparatus 30 has three flow conduits, 32X, 32Y and 32Z (see
Alternatively, multiple flow conduits may have different widths or flow cross-sections for providing multiple breached flow conduits with different flow capacities. Apparatus 40 has small flow conduit 42S and large flow conduit 42L (see
Lateral expansion of the expanding flow conduits may be resisted during the applied pressure by strong lateral seals. The lateral seals preferably extend along the sides of the elongated flow conduits from the storage chamber to the ambient. Apparatus 40 has three lateral seals, 44S and 44L and 44M (indicated by solid parallel lines). Lateral seal 44S prevents small flow conduit 42S from expanding into perimeter 40P causing a long and random perimeter breach. Lateral seal 44L prevents large flow conduit 42L from expanding into chamber 40C causing a long and random chamber breach. Middle lateral seal 44M located between the small and large flow conduits prevents the conduits from expanding into one another. The three lateral seals offer stiff resistance to lateral expansion, directing the pressure force within the flow conduits to cause expansion at the ends. Therefore, expansion due to the directed pressure is primarily outward towards the perimeter of the apparatus, and inward towards the chamber. The lateral seals may be stronger then either the inner seal or the outer seal due to a higher temperature and/or pressure and/or dwell-time during seal formation.
Alternatively, the lateral seals may be weak (soft) to permit lateral expansion during the applied pressure. Apparatus 50 (see
The access region within the apparatus may be located at a corner or between corners. Apparatus 30 has at least one corner 37, and the flow conduits positioned proximate that corner (see
In some applications ambient atmosphere must be kept out of the storage chamber. Apparatus 60 has out-only flow valve 65D positioned in flow conduit 62D (see
The flow conduit apparatus may have multiple storage chambers for storing multiple fluids. In a three chamber embodiment (
Alternatively, in some embodiments multiple stored fluids may be accessed simultaneously. Apparatus 80 has two storage chambers 80L and 80R (see
The apparatus may have a discharge spout extending from the breached flow conduit for guiding the discharge of the stored fluid. Discharge spout 23 (see
The flow conduit may extend across the entire width of the apparatus to provide a large breach for quickly discharging the stored fluid. Apparatus 90 has flow conduit 92 which extends between end corners 97 (see
